Best of luck to you, Travis. I hope you can find a way to make 400hp survivable. Then I'd want to know what the 25, 50 and 100km engine looks like.
Rub87, I never saw the cam. I know who made it, and I saw another similar cam, which was a modified OEM cam. Within the stock cam lobe I don't think it could have been made to work well. The original owner pulled them before shipping the cylinder head. The valve damage was limited to the ends of the valves from non-rotation. I should look the pics up again. What I do know, if the exhaust side was damaged and the intake was completely normal. Since I expect both cams would have been similar in height, I can't imagine the lift was so extreme to cause spring bind.
I think making an engine survive under some extreme runs is the challenge. There are engines I have destroyed in single outings; performance, ET's and trap speed was the only goal. Tear them apart at the end of each run... that was the norm. I don't want that for my road 'fun car'.
The intent we prefer to design now, is survivability within the confines of the engine. After all, the original goal of these vehicles was extreme long life, with high fuel economy. Sure, you can push the power, but when that happens, not many talk about the head lift, warp, burned pistons, bent rods and other toasted internals, when they happen.
It's a different kind of gambling. Talk about the success, but avoid the talk of failures. That you are doing differently, Travis. Sorry to hear of your issues. I guess I've walked away with my pockets emptied enough that now, I like an engine to stay together for many years and many, many miles before I have to do any maintenance to them.
40 1/4 mile pulls and your engine might have run 10 minutes. I want to know how it acts when it's gone 10,000 hours. I believe in the stock state, the engine is capable of that kind of mileage.
The head I saw was claimed to only have 6,000km. It was quickly turned into junk. I only know what I have seen and it's not good.
